CC   -!- FUNCTION: IGPS catalyzes the conversion of PRFAR and glutamine to
CC       IGP, AICAR and glutamate. The HisH subunit catalyzes the
CC       hydrolysis of glutamine to glutamate and ammonia as part of the
CC       synthesis of IGP and AICAR. The resulting ammonia molecule is
CC       channeled to the active site of HisF. {ECO:0000255|HAMAP-
CC       Rule:MF_00278}.
